I am very carefull of liability and safety issue’s from frivilous lawsuit’s and would not jepordise safety or the chance of a lawsuit! My Dad practiced law for 50 year’s and have seen many time’s unfounded lawsuit’s. The minor damage is only an area no bigger than your finger nail 10 thousanths smaller than machine spec’s brass is very soft and not large enough to compromise structural integrity. Still more tread’s and metal than a 200 bar valve which is more common.
